The Association of Glycemic Index, Glycemic Load, and Daily Carbohydrates Intake with the Risk of Hepatocellular Carcinoma: A Systematic Review and Meta-Analysis.

Background: Glycemic index (GI), glycemic load (GL) and daily carbohydrates intake have been associated with a variety of cancers, but their implications in hepatocellular carcinoma (HCC) remain controversial. The purpose of our study is to investigate the association of GI, GL and daily carbohydrates intake with the risk of HCC. Methods: Systematic searches were conducted in PubMed, Embase and Web of Science until November 2020. According to the degree of heterogeneity, random effect model or fixed effect model was chosen to obtain the pooled relative risks (RRs) and corresponding 95% confidence intervals (CIs). Results: Four cohort studies and three case-control studies were eventually included. The pooled results showed no significant association of GI (RR = 1.11, 95% CI = 0.80-1.53), GL (RR = 1.09, 95% CI = 0.76-1.55), and daily carbohydrates intake (RR = 1.09, 95% CI = 0.84-1.32) with the risk of HCC in the general population. Subgroup analysis revealed that in hepatitis B virus (HBV) or/and hepatitis C virus (HCV)-positive group, GI was irrelevant to the risk of HCC (RR = 0.65, 95% CI = 0.32-1.32), while a high GL diet was associated with a higher risk of HCC (RR = 1.52, 95% CI = 1.04-2.23). In contrast, in HBV and HCV-negative group, both GI (RR = 1.23, 95% CI = 0.88-1.70) and GL (RR = 1.17, 95% CI = 0.83-1.64) were not associated with the risk of HCC. Conclusion: A high GL diet increases the risk of HCC in those with viral hepatitis. A low GL diet is recommended for them to reduce the risk of HCC.

Terminal trajectory of HbA1c for 10 years supports the HbA1c paradox: a longitudinal study using Health and Retirement Study data.

Objectives: We aimed to assess the potential time-varying associations between HbA1c and mortality, as well as the terminal trajectory of HbA1c in the elderly to reveal the underlying mechanisms. Design: The design is a longitudinal study using data from the Health and Retirement Study. Setting and participants: Data were from the Health and Retirement Study. A total of 10,408 participants aged ≥50 years with available HbA1c measurements at baseline (2006/2008) were included. Methods: Longitudinal HbA1c measured at 2010/2012 and 2014/2016 were collected. HbA1c values measured three times for their associations with all-cause mortality were assessed using Cox regression and restricted cubic splines. HbA1c terminal trajectories over 10 years before death were analyzed using linear mixed-effect models with a backward time scale. Results: Women constitute 59.6% of the participants with a mean age of 69 years, with 3,070 decedents during the follow-up (8.9 years). The mortality rate during follow-up was 29.5%. Increased mortality risk became insignificant for the highest quartile of HbA1c compared to the third quartile (aHR 1.148, 1.302, and 1.069 for a follow-up of 8.9, 6.5, and 3.2 years, respectively) with a shorter follow-up, while it became higher for the lowest quartile of HbA1c (aHR 0.986, 1.068, and 1.439 for a follow-up of 8.9, 6.5, and 3.2 years, respectively). Accordingly, for both decedents with and without diabetes, an initial increase in HbA1c was followed by an accelerating terminal decline starting 5-6 years before death. Conclusions and implications: The time-varying association between HbA1c and mortality mapped to the terminal trajectory in HbA1c. High and low HbA1c may have different clinical relationships with mortality. The HbA1c paradox may be partially explained by reverse causation, namely, early manifestation of death.

Caffeine intake is associated with less severe depressive symptoms in noncancer populations: an analysis based on NHANES 2007-2016.

Depression and cancer are both prevalent diseases worldwide. Numerous cancer patients experience psychological illnesses, especially depression, following a malignancy's dismal prognosis. Although some research has suggested that caffeine may be protective against depressive symptoms, it is still unclear how caffeine and cancer patients are related. Thus, we hypothesized that moderate daily caffeine intake may reduce the risk of depression in both the cancer and noncancer populations. Data were extracted and combined from the National Health and Nutrition Examination Survey from 2007 to 2016. After controlling for potential confounding factors, interaction effects analysis was used to clarify the interaction between caffeine and cancer on depressive symptoms. Linear regression analysis and restricted cubic splines were used to further analyze the relationship between caffeine and depression in cancer and noncancer populations. A total of 24,145 participants were included in the analysis. In the noncancer population, the quartile 3 group of caffeine intake showed a negative association between caffeine intake and Patient Health Questionnaire-9 (PHQ-9) scores (ß = -0.23, 95% confidence interval, -0.45 to -0.01; P = .041). No association between caffeine intake and PHQ-9 scores was observed in the cancer population. In both cancer and noncancer populations, restricted cubic splines indicated a nonlinear trend between caffeine and PHQ-9 scores, with the lowest PHQ-9 scores when caffeine intake was 119.52 mg. In the noncancer population, moderate daily caffeine intake (quartile 3 group; range, 119.5-236.5 mg) was associated with reduced depressive symptoms, whereas in the cancer population, no association was found between caffeine intake and depression.

Systemic therapy with or without locoregional therapy for advanced hepatocellular carcinoma: A systematic review and network meta-analysis.

We aim to identify the optimal treatment option of systemic therapy with or without locoregional therapy for advanced hepatocellular carcinoma (HCC). Outcomes of interest include overall survival (OS), progression-free survival (PFS), objective response rate (ORR), grade 3-4 treatment-related adverse events (TRAEs), and incidence of treatment discontinuation due to AEs. The surface under the cumulative ranking curve (SUCRA) probability values were applied to rank the interventions. 23 randomized-controlled trials including 14,303 patients with advanced HCC were included. Lenvatinib plus transcatheter arterial chemoembolization (TACE) ranked best regarding OS benefit (SUCRA: 0.99). Immuno-oncology (IO)-multikinase inhibitor (MKI)/vascular endothelial growth factor (VEGF) inhibitor combinations had a higher probability of providing better OS than IO-IO combinations. IO monotherapies demonstrated superior safety profile while combination therapies caused more toxicity in general. We conclude that combination therapies achieve remarkable efficacy in patients with advanced HCC and clinical decision making requires a careful balance of efficacy versus risk.

Regional and sex differences in the mortality risk associated with primary liver cancer in obesity: A systematic review and meta-analysis.

OBJECTIVE: Obesity has increasingly become a prominent public health problem. Although some studies have shown that obesity is associated with the risk for primary liver cancer (PLC)-related mortality, the regional and sex differences are not clear. The aim of this meta-analysis was to further elucidate the influence of obesity on PLC prognosis from multiple aspects. METHODS: This study used a systematic literature search on PubMed, Embase, Cochrane Library, Web of Science, Sinomed, and CNKI for eligible studies evaluating the effects of obesity on the prognosis of PLC. Data on PLC-related mortality, all-cause mortality, or recurrence should be available to obtain, and studies providing regional, or sex specificity are of concern. Hazard ratios (HRs) and the corresponding 95% confidence intervals (CIs) were used to assess the pooled risk. RESULTS: Obesity is strongly associated with an increased risk for PLC-related mortality. A significant regional difference was observed (North America: HR, 1.57; 95% CI, 1.06-2.34; Europe: HR, 1.53; 95% CI, 1.08-2.16; Asia: HR, 1.05; 95% CI, 0.92-1.19; Oceania: HR, 1.13; 95% CI, 0.76-1.67). A stronger association between excess body mass index (BMI) and an increased risk for PLC-related mortality was demonstrated in men compared with women (men: HR, 1.87; 95% CI, 1.25-2.77; women: HR, 1.22; 95% CI, 1.00-1.47). No association was observed in the analysis between obesity and all-cause mortality and recurrence risk in PLC (all-cause mortality: HR, 1.01; 95% CI, 0.96-1.06; recurrence risk: HR, 1.00; 95% CI, 0.88-1.15). CONCLUSION: This study demonstrated a stronger association between obesity and PLC-related mortality in North America and Europe and among men.

Anthropometric indicators of adiposity and risk of primary liver cancer: A systematic review and dose-response meta-analysis.

BACKGROUND AND AIMS: Adiposity is associated with an increased risk of primary liver cancer (PLC). As the most commonly used indicator of adiposity, the body mass index (BMI) has been questioned for its limitations in reflecting visceral fat. This study aimed to investigate the role of different anthropometric indicators in identifying the risk of PLC by accounting for potential non-linear associations. METHODS: Systematic searches were conducted in the PubMed, Embase, Cochrane Library, Sinomed, Web of Science, and CNKI databases. Hazard ratios (HRs) and the corresponding 95% confidence intervals (CIs) were used to assess the pooled risk. The dose-response relationship was assessed using a restricted cubic spline model. RESULTS: Sixty-nine studies involving more than 30 million participants were included in the final analysis. Regardless of the indicator used, adiposity was strongly associated with an increased risk of PLC. When comparing the HRs per 1-standard deviation increment across indicators of adiposity, the association was strongest for waist-to-height ratio (WHtR) (HR = 1.39), followed by waist-to-hip ratio (WHR) (HR = 1.22), BMI (HR = 1.13), waist circumference (WC) (HR = 1.12), and hip circumference (HC) (HR = 1.12). A strong non-linear association was observed between each anthropometric parameter and the risk of PLC, regardless of whether the original or decentralised value was used. The positive association between WC and PLC risk remained substantial after adjusting for BMI. The incidence of PLC was higher with central adiposity (52.89 per 100,000 person-years, 95% CI = 50.33-55.44) than general adiposity (39.01 per 100,000 person-years, 95% CI = 37.26-40.75). CONCLUSION: Central adiposity seems to contribute more to the development of PLC than general adiposity. A larger WC, independent of BMI, was strongly associated with the risk of PLC and might be a more promising predictive indicator than BMI.

Effect of liver metastasis on the efficacy of immune checkpoint inhibitors in cancer patients: a systemic review and meta-analysis.

Liver metastasis is a frequent phenomenon in advanced tumor disease. Immune checkpoint inhibitors (ICIs) are a new class of therapeutics that can improve the prognosis of cancer patients. The purpose of this study is to elucidate the relationship between liver metastasis and survival outcomes of patients receiving ICIs treatment. We searched four main databases, including PubMed, EMBASE, Cochrane Library, and Web of Science. Overall survival (OS) and progression-free survival (PFS) were the survival outcomes of our concern. Hazard ratio (HR) with 95% confidence interval (CI) were used to evaluate the relationship between liver metastasis and OS/ PFS. Finally, 163 articles were included in the study. The pooled results showed that patients with liver metastasis receiving ICIs treatment had worse OS (HR=1.82, 95%CI:1.59-2.08) and PFS (HR=1.68, 95%CI:1.49-1.89) than patients without liver metastasis. The effect of liver metastasis on ICIs efficacy differed in different tumor types, and patients with urinary system tumors (renal cell carcinoma OS: HR=2.47, 95%CI:1.76-3.45; urothelial carcinoma OS: HR=2.37, 95%CI:2.03-2.76) had the worst prognosis, followed by patients with melanoma (OS: HR=2.04, 95%CI:1.68-2.49) or non-small cell lung cancer (OS: HR=1.81, 95%CI:1.72-1.91). ICIs efficacy in digestive system tumors (colorectal cancer OS: HR=1.35, 95%CI:1.07-1.71; gastric cancer/ esophagogastric cancer OS: HR=1.17, 95%CI:0.90-1.52) was less affected, and peritoneal metastasis and the number of metastases have a greater clinical significance than liver metastasis based on univariate data. For cancer patients receiving ICIs treatment, the occurrence of liver metastasis is associated with poor prognosis. Different cancer types and metastatic sites may hold a different prognostic effect on the efficacy of ICIs treatment in cancer patients.

Identification of the most effective subgroup of advanced hepatocellular carcinoma from immune checkpoint blocker treatment: a meta-analysis.

Aims: This work was designed to identify the subgroup of advanced hepatocellular carcinoma (HCC) patients for whom treatments containing immune checkpoint blockers (ICBs) were most effective. Materials & methods: A meta-analysis was performed to explore the subgroup population with the greatest benefit of treatments containing ICBs. Results: A total of 2228 patients from four randomized control trials were included. Treatments containing ICBs had better overall survival, progression-free survival and higher objective response rate over treatment without ICBs. Subgroup analysis revealed that treatments containing ICBs were highly effective in improving the overall survival of males, patients with macrovascular invasion and/or extrahepatic spread and viral-related HCC patients. Conclusion: Treatments containing ICBs are more effective for males, patients with macrovascular invasion and/or extrahepatic spread and viral-related HCC patients.

Immune checkpoint blockers (ICBs) have significantly improved the prognosis of advanced cancers. However, some patients still cannot benefit from ICBs. The use of ICBs in the treatment of advanced hepatocellular carcinoma (HCC) started late. The subgroup of advanced HCC patients that will benefit most from treatments containing ICBs is still largely unknown. Therefore, a meta-analysis (meta-analysis is a statistical method used to compare or synthesize research results on the same scientific problem) was performed to explore the subgroup population with the greatest benefit of treatments containing ICBs (ICBs alone or in combination with anti-VEGF agents). The results show that treatments containing ICBs are more effective for males, patients with macrovascular invasion and/or extrahepatic spread and viral-related HCC patients.

The Predictive Potential of the Baseline C-Reactive Protein Levels for the Efficiency of Immune Checkpoint Inhibitors in Cancer Patients: A Systematic Review and Meta-Analysis.

Background: The relationship between baseline C-reactive protein (CRP) level and the prognosis of cancer patients receiving immune checkpoint inhibitor (ICI) treatment remains controversial. The aim of this meta-analysis was to clarify whether baseline CRP level can serve as a biomarker to predict the efficiency of ICI therapy. Methods: All associated articles published in the Cochrane Library, EMBASE, and PubMed databases from the inception of the database to December 30, 2021, were retrieved. Progression-free survival (PFS) and overall survival (OS) outcomes were meta-analyzed using the random-effects model and adjusted using the trim-and-fill method because of publication bias. Results: Thirty-three studies (6,124 patients) conducted between 2013 and 2021 were identified. The pooled outcomes implied that high baseline CRP level patients had significantly worse OS (adjusted pooled value for univariate and multivariate analysis outcomes: HR = 1.48, 95% CI = 1.41-1.56; HR = 1.46, 95% CI = 1.34-1.59) and PFS (adjusted pooled value for univariate and multivariate analysis outcomes: HR = 1.29, 95% CI = 1.15-1.45; HR = 1.20, 95% CI = 1.02-1.40) than low baseline CRP level patients, irrespective of cancer or ICI type. Further analysis indicated that 1 mg/dl was appropriate as a cutoff value for determining the low or high level of baseline CRP to predict the OS or PFS of cancer patients receiving ICI treatment (univariate analysis: HR = 1.56, 95% CI = 1.24-1.97, P = 0.909; multivariate analysis: HR = 1.58, 95% CI = 1.23-2.03, P = 0.521). Conclusions: High baseline CRP level (>1 mg/dl) may be an indicator for worse OS and PFS of cancer patients treated with ICIs. More high-quality prospective studies are warranted to assess the predictive value of CRP for ICI treatment.
